The Vevor aquarium vacuum gravel cleaner is designed to simplify routine fish tank maintenance with quick water changes and gravel cleaning. It uses water pressure instead of electricity or manual pumping, helping remove dirty water efficiently. A 12.6" gravel tube with internal filter net helps clean waste while reducing the chance of sand entering the hose. The 30' PVC hose offers flexible reach for tanks located farther from a faucet. Brass faucet adapters in multiple sizes improve compatibility with common bathroom, garden, and kitchen faucets.
